Standard Users Last Activity Column

Can you add a column to the users management screen to be able to sort by last activity. Since we have to pay for standard users I would like an easier way to sort and deactivate users who no longer need access.

I was just hitting the same snag, I have a lot of standard user and no good way of finding out wich ones are still active. I tried to see if I could make a report wich showed me this data. I turned out, I cant. This is really a hygiene factor, and you should adress this in some way, either add another column, or ad the distintion between Power and standard user in the login reports section, along with better time value filtering. (in the last 30 days, 90 days, year etc.)

As of now I have to click into each and every standard user to check if the account is in use, or not. This is not good enough, and this should be an easy fix.
